Cannot connect to environment on another PC

I have Service studio version 10.0.502.0 on both my laptop and newly set up PC. I am able to connect to my personal environment xxx.outsystemscloud.com on my laptop but cannot connect when using my PC. The error message says "Invalid username/password".

I thought maybe I couldn't connect to xxx.outsystemscloud.com simultaneously on two machines, so I logged out from my laptop but I still got the same error message on my PC when I tried to connect.
